Specification of Zettcrs Patent.

Patented July ill. tell To all whom it may concern.

Be it known that L'Tnnooonn Lrxnnnsnne, a. citizen of the United States. residing at Grandview Heights, in the county of Franklin and State certain new. and useful Improvements in Carburetors, of which the following is a specification.

This invention relates to carburetors of the type wherein the'fuel is vaporized di opposed to the atomizin'g effect-Where the fluid is drawn into the repel-icing chamber i i-spray form. In carrying out this direct vaporizing action, I depend on the capillary attraction of the fuel fluid acting in connection with an absorbentmember of some nature.

The main object of my invention, therefore, resides in a novel arrangement of absorbent members interposed in the path of the incoming air, the flow of which is created by. the suction eiiect of an engine and to thereby convert this infiowingair into a combustible mixture.

A further object of'rny invention resides in the valve structure used and also in the particular arrangement of this valve structure with respect to the absorbent unit and the nature of the vaporizing body through which the 'admitted air enters. This valve structure is arranged so that the sectional area of'the vaporizing body may be varied to regulate the Flow of air through this ody and at the same time to also regulate the area of the absorbent unit exposed to i the action of the inflowiug air. This unit is sectional area of the amount also. constructed and arranged so that the area exposed produces a richer mixture for.

heavy loads than it does for light ones. This arrangement is produced by a structure 'Whereby the degree of exposure of the unit 18 not in direct proportion to the increase in the vaporizing body, but of the unit exposed is in a greater amount than in a direct proportion to the sectional area of the vaporizing body.

The preferred embodiment of my invention is shown in theaccompanying sheet of drawings, in which similar characters of reference designate corresponding parts, and in which:

Figure 1 vertical longitudinal section of my improved type-of carburetor,

Fig. 2 is a transi ersc vertical section taken on bus 2-2 of Fig. i, and,-

of Ohio,-have invented V Fig. 3 is a horizontal section taken on line 33 of Fig. 2.

In these several views the vaporizing body is designated by the reference numeral 1 and is shown as being formed of a casting 2 quadrangular in shape and covered by v a closure 3. The rear end of this vaporizing body is open to permit the inflow oi air and in the drawing, the conduit 4 is shown as forming this open end it being understood that this conduit may lead to any desired point to take in the fresh air. The opposite end 5 of the vaporizing body is also open and leads into the conduit 6, the latter leading to the cylinders of the engine in any desired manner. The float bowl 7 is shown as being secured to the underside of the vaporizing I supplied. this float bowl through the pipe 8. The flow of fuel through the pipe 8 is governed by the usual type of valve 9 under :the influence of valve being connected by means of the interposed lever 11 pivoted as is shown at 12.

Located Within the vaporizing body in longitudinal array are a plurality of ab-' sorbent members 13 all slightly spaced from each other. These members 13 may beef any desiredmaterial, it being, ct course, understood that the quality of absorbent member regulates the amount of fluid they are able to retain. Fluid is supplied these absorbent members through capillary attra 0- tion by means of the fingers 14 leading down into the iiuid chamber 7 and into the fluid Within this fluid chamber. The sectional area of the conduit 6 is preferably arranged to be equal to that taken through the vaporizing body 'Whenall of the absorbent members 13 are fully exposed to the action of the incoming air. In order to regulate the quality of mixture, I have provided a valve in the nature of a shutter 15 slidable over the top ofthe triangular absorbent members as is shown and guided by means of the guide Ways 16. This shutter extends through the bottom side of the vaporizing body and is attached to the throttling handle in any desired manner as, for instance, by means of the cable shown at 17.

The absorbent members 13 are made triangular in shape in order that the amount or surface exposed as the valve 15 is retracted will not vary in direct ratio with the amount of. opening created by this valve through the vaporizing chamber. By this body and fuel is' the float 10, the float and means the mixture may be enriched as the load increases. I Also, it will be noted that the valve 15 not only serves to govern the amount of absorbent member area exposed, but also governs the opening through which the incoming air may pass and in this manner serves in the additional capacity of a throttle.

From the foregoing description, taken 1'11 connection with the accompanying sheet of drawing, it will be apparent that I have rpvided a type of carburetor wherein the uni fuel is vaporized by the direct action of the air on the absorbent members. These absorbent members are saturated by means of capillary attraction and the nature of the explosive mixture regulated by means of the throttle valve 15. I lay particular stress on the location of this valve between the absorbent members and the open end of the vaporizing body for the reason that it serves the two fold purpose of regulating the amount of opening through the vaporizing body and also regulates the amount of surface of absorbent members exposed.

What I claim, is: 1. A carbureter comprisinga vaporizing chamber open at one end for the admission v of air and at the other end for the outflow of the mixture, an absorbent member within said chamber and also in communication with the"source of fuel supply, and a valve structure interposed between said absorbent.

member and said first mentioned open end, said valve'being mounted and arranged so that an opening movement thereof to admit more air also exposes more of said absorbent member to the action of the inflowing air and vice versa.

2. A carbureter comprising a vaporizing chamber open at one end for the admission of air and at the other end for the outflow of the mixture, an absorbent member within said chamber and also in communication with a source of fuel supply, and a throttle valve structure within said chamber and interposed between said absorbent member and the first named open end arranged to vary the open sectional area of said body to regulate the flow of air and at the same time to vary the area of said member exposed to the action of the infiowing air.

' 3. A carbureter con arising a vaporizing tional area of said body to regulate the flow of air and at the same time to vary the area of said members exposed to the action of the infiowing air.,

4:. A carbureter comprising a vaporizing body open at one end forthe admission of air and at the other end for the outflow ofthe mixture, a plurality of spaced absorbent members arranged side by side and extending longitudinally Within said body, said members being in communication with a' source of fuel supply, and a shutter valve slidable in and out of said body interposed between said members and said first named open end to vary the open sectional area of said body to regulate the flow of air and at the same time to vary the area of said members exposed to the action of the inflowing air.

5. A carbureter comprising a ,vaporizing body open at one end for the admission of air and at the other end for the outflow of the mixture, a float bowl carried by theunderside of said body, a plurality of spaced triangularly shaped longitudinally arranged absorbent members'located side by side within said body, all of said members being in communication with the interior ofsaid bowl, and a shutter valve arranged to slide on an incline over the top of said members, said valve being interposed in said body between said members and said first named open end to vary the sectional area of said body to regulate thenfiow of air and at the same time to vary the area of said members exposed to the action of the inflowing airs In testimony whereof I afiix my signature in presence of two witnesses.
